QT QThread基本使用

TcpClient.h

#ifndef TCPCLIENT_H
#define TCPCLIENT_H
#include <QThread>

class TcpClient: public QThread{
    
    

public:
    static TcpClient& getInstance()
    {
    
    
        static TcpClient instance;
        return instance;
    }

    TcpClient();

private:
    void run();
};

#endif // TCPCLIENT_H

TcpClient.cpp

#include "TcpClient.h"

TcpClient::TcpClient()
{
    
    

}
void TcpClient::run(){
    
    
    qDebug("==TcpClient==run=====");

}

   TcpClient::getInstance().start();
